Libarchive

libarchive's development was started in 2003 as part of the FreeBSD project.{{cite web |url=https://github.com/libarchive/libarchive/wiki/ReleaseNotes |title=ReleaseNotes |access-date=2023-05-25 |website=GitHub |archive-url=https://web.archive.org/web/20220312005639/https://github.com/libarchive/libarchive/wiki/ReleaseNotes |archive-date=2022-03-12 |url-status=live |language=en}} During the early years it was led by the FreeBSD project, but later it became an independent project.{{cite web |url=https://github.com/libarchive/libarchive/wiki/ReleaseEngineering |title=ReleaseEngineering |access-date=2023-05-25 |website=GitHub |archive-url=https://web.archive.org/web/20220430100141/https://github.com/libarchive/libarchive/wiki/ReleaseEngineering |archive-date=2022-04-30 |url-status=live |language=en}} It was first released with FreeBSD 5.3 in November 2004.{{cite web |url=https://github.com/libarchive/libarchive/wiki/LibarchiveUsers |title=LibarchiveUsers |access-date=2023-05-25 |website=GitHub |archive-url=https://web.archive.org/web/20221128123136/https://github.com/libarchive/libarchive/wiki/LibarchiveUsers |archive-date=2022-11-28 |url-status=live |language=en}}

libarchive automatically detects and reads archive formats.{{man|3|libarchive|FreeBSD}} If the archive is compressed, libarchive also detects and handles compression formats before evaluating the archive.{{r|name="libarchive-man"}} libarchive is designed to minimize the copying of data internally for optimal performance.{{cite web |url=https://github.com/libarchive/libarchive/wiki/ZeroCopy |title=ZeroCopy |access-date=2023-05-25 |website=GitHub |archive-url=https://web.archive.org/web/20220430121404/https://github.com/libarchive/libarchive/wiki/ZeroCopy |archive-date=2022-04-30 |url-status=live |language=en}}

libarchive provides command-line utilities called bsdtar and bsdcpio.{{r|name="www.libarchive.org"}} These are complete re-implementation based on libarchive.{{man|1|bsdtar|FreeBSD}}{{man|1|bsdcpio|FreeBSD}} These are the default system tar and cpio on FreeBSD, NetBSD, macOS and Windows.{{r|name="LibarchiveUsers"}}

There is also bsdcat, designed to decompress a file to the standard output like zcat.{{man|1|bsdcat|FreeBSD}}

libarchive was originally developed for FreeBSD, but is also used in NetBSD and macOS as part of those operating systems.{{r|name="LibarchiveUsers"}}

bsdtar has been included in Windows since Windows 10 April 2018 Update.{{cite web |date=2019-03-21 |title=Tar and Curl Come to Windows! |url=https://techcommunity.microsoft.com/t5/containers/tar-and-curl-come-to-windows/ba-p/382409 |url-status=live |archive-url=https://web.archive.org/web/20230415164646/https://techcommunity.microsoft.com/t5/containers/tar-and-curl-come-to-windows/ba-p/382409 |archive-date=2023-04-15 |access-date=2023-05-25 |website=Microsoft Community Hub |language=en}} In May 2023, Microsoft announced Windows 11 will natively support additional archive formats such as 7z and RAR via libarchive.{{cite web |last=Panay |first=Panos |author-link=Panos Panay (Microsoft) |date=2023-05-23 |title=Bringing the power of AI to Windows 11 - unlocking a new era of productivity for customers and developers with Windows Copilot and Dev Home |url=https://blogs.windows.com/windowsdeveloper/2023/05/23/bringing-the-power-of-ai-to-windows-11-unlocking-a-new-era-of-productivity-for-customers-and-developers-with-windows-copilot-and-dev-home/ |url-status=live |archive-url=https://web.archive.org/web/20230525120145/https://blogs.windows.com/windowsdeveloper/2023/05/23/bringing-the-power-of-ai-to-windows-11-unlocking-a-new-era-of-productivity-for-customers-and-developers-with-windows-copilot-and-dev-home/ |archive-date=2023-05-25 |access-date=2023-05-25 |website=Windows Developer Blog |language=en}}
